How investment dealers operate, how they earn revenue, and how principal, agency, and clearing functions differ.
Investment dealers are central market intermediaries. They help issuers raise capital, help investors trade existing securities, and provide the research, sales, execution, inventory, and operational systems that make the market function.
An investment dealer can play several roles at once:
That is why dealers matter in both capital formation and day-to-day market liquidity.
The old labels vary across textbooks, but the practical distinctions are clearer if you think in terms of client focus and business model.

These firms focus on institutional clients such as:
Institutional business often involves large block trades, research, market intelligence, and capital-markets activity.
Many major firms operate across both retail and institutional lines. They may combine:

Control and support functions such as:
Operational processing such as:
The point is not memorizing an org chart. The point is understanding that client-facing advice and trading rely on a large control and operations structure behind them.
Canadian market infrastructure reduces the need for each firm to settle every trade separately with every counterparty.
In Canada, central clearing and settlement infrastructure is provided through CDS. The move to T+1 settlement on May 27, 2024 shortened the normal settlement cycle for most Canadian listed securities and increased the need for faster allocations, confirmations, and funding.
